摘要： An electrochemical cell is provided comprising: a can (312) for containing electrochemically active materials, the can (312) including an open end and a closed end; a first outer cover (345) positioned across the open end of the can (312); a collector (340) electrically coupled to the first outer cover (345) and extending internally within the can (312) to electrically contact one of the positive and negative electrodes; and an annular seal (330) having an L-shaped cross section disposed between the can (312) and the first outer cover (345) for electrically insulating the can (312) from the first outer cover (345) and creating a seal between the first outer cover (345) and the can (312). A pressure relief mechanism such as a groove (370) is preferably formed in the closed end of the can (312). Also provided is a collector and seal assembly for such electrochemical cell, and a method of assembling the electrochemical cell. The cell construction allows a large internal volume to be available for containing electrochemically active materials. The collector may have the shape of a nail and the seal may have a J-shaped cross section.
